Stop the presses! I want to make sure I understand what's happening here... Are we saying that Al Gore may have gotten it wrong in his global warming movie? Wow, that's a real brain bender. Does this also call into question Gore's claims that he invented the Internet? Stop the presses! Are a lot of guys who aren't climatologists making ostensibly authoritative claims about climatology? Gore made a few unwarranted leaps of logic, and made a few fallacious arguments in An Inconvenient Truth. True. But peer-reviewed authorities on climatology all agree that the current greenhouse gas situation is vastly increasing the risk of an abrupt climate change. I just took a second look, and these guys are geologists. At least they're scientists, but of all species of scientists, I would trust geologists the least on the issue of greenhouse gases. Geologists study the composition of earth. Oil and coal companies regularly hire geologists to help them find and study their product. Many geologists certainly have a large vested interest on those companies that regularly employ them. Therefore, they would be more likely than others to fall to the "dark side" and lie to the public and increase their wealth. Am I totally off base here? Let me, buches, explain you that only small part of geologists are hired by oil companies. Many more geologists work to explore metals and nonmetals, drinking and mineral water, for construction, and, bye the way, for environmental companies to keep our water and soil clear, They drill more than 1000 wells per one oil well. Investigating the composition of the Earth, they cannot hide the endless facts on past grandiose climate changes, dramatic variations in composition of the atmosphere, powerful natural forces, and catastrophic events occurred. Nobody knows why. Despite the fact, that the IPCC excluded geologic sources and entire geologic past from their so called models (you can see it, f... You may be right, and perhaps the conflict of interest that I mentioned only occurs for a small number (if any) of geologists, but I still have lingering suspicions. I didn't mean to demean geology as a valid science, and I know that their contributions to our wealth of knowledge are great. Geology, as a valid science, has many peer-reviewed journals. Are you aware of any such reliable source in geology that contradicts the National Academies' conclusions? My research has yielded no conflicts from the following: in a chaotic system, such as the earth’s climate, an abrupt climate change always could occur. Howe... It is now the consensus...No consensus at all Is that all you can do? Make an unsupported claim? I thought you might be fun to debate, but apparently you're just another blinded by prejudice. a study in the journal Science by the social scientist [Naomi] Oreskes claimed that a search of the ISI Web of Knowledge Database for the years 1993 to 2003 under the key words "global climate change" produced 928 articles, all of whose abstracts supported what she referred to as the consensus view. A British social scientist, Benny Peiser, checked her procedure and found that only 905 of the 928 articles had abstracts at all, and that only 13 of the remaining 905 explicitly endorsed the so-called consensus view. Full text read at http://meteo.lcd.lu/globalwarming/Lindzen/no_consensus.html To debunk the myth on consensus, see: http://www.businessandmedia.org/specialreports/2007/globalwarming/SkepticalScientists.asp Is there really a scientific community that is debating all these issues and then somehow agreeing in unison? ttp://meteo.lcd.lu/globalwarming/Lindzen/no_consensus.html A bunch of people's names who apparently say there is no consensus, without any actual argument to the merits of my claim, is a mere appeal to authority. You might as well have just said, "nu-uh." I asked for a peer-reviewed report in a scientific publication that disputes the consensus of arguments presented by the IPCC, the National Academies, the NOAA, the National Research Council, and every article I have found in journals like Science and Nature. I could debunk the meteorologist's claims in the Wall Street Journal editorial point-by-point, but that has been done to death. ... What did you show me? I did not find there a fact, just the same verbiage on ice melting and sea level rise threat. Even Lindzen no longer questions that greenhouse gas emissions are causing global warming.As there is no doubt that CO2 is green-house gas, no doubt it contributes to warming. But how much, among other more powerful controls that we don't have reliable quantative science about- that is the question. What does he know about real mechanisms of sea regressions and transgressions? Modern science can only describe the phenomena reading outcrops and well-logs.But his claim on climate forecasts stroke me down. Ther rudimentary models does not explain temperature beha... amgumen = denialll? Interesting. Before you start making requests of me, I'm still waiting for you to provide what you keep claiming is so easy to find: a single, peer-reviewed report in a scientific publication that disputes the consensus of arguments presented by the IPCC, the National Academies, the NOAA, the National Research Council, and the other various peer-reviewed articles such as the ones I have already posted. I could debunk the meteorologist's claims in the Wall Street Journal editorial point-by-pointYou could? But your modesty was the obstacle? Based on the article alone you reffers to, one can see there is no consensus on global warming causes. On the contrary, there is very serious debates - to death By consensus, I don't mean every single person in the world is absolutely certain about the outcome. I mean that (from my research) it appears that every peer-reviewed scientific journal on the topic has a very similar conclusion related to anthropogenic global warming. A list of names and a newspaper op-ed don't dispute my claim. Neither does a bald assertion that I'm lying. You're a geologist. You have seen a science paper before. You know what I'm talking about. Sorry, guys, I interrupted your conversation. It was not hard to confuse one clip with another because of the same topic, consensus. I don't mean every single person in the worldNo, Buches, you are boggling. You know for sure that there are a lot of single persons who contributed to climate science significantly, like prof Lindzen. I mean numerous physicists, chemists, geologists, hydrologists, mathematicians. And your filtration (climatologist-nonclimatologist) is not relevant with respect to such a complex area of knowledge like climate science. You are likely also know that principle of majority in science (and not only) does not work. A perfect support to this is the ... amgumen, if I appear to just be being stubborn, I'm sorry. I really want to know the science. You're not the only one I'm having similar conversations with, and I'm honestly searching peer-reviewed journals, and despite my research and my requests to you and others, I have yet to find a peer-reviewed scientific study in any field that disputes what I'm calling the consensus. All I'm finding is blogs, op-eds, energy-company-funded think tanks, etc. saying that the entire science community is in disarray, while my research of the science yields nothing but harmony. If there's any data, any study, any science, ANYWHERE, against the consensus, please help me to find it, and don't just say (again) that I'm ignoring the science. Buches, let's return to Geology, as a valid science, has many peer-reviewed journals. Are you aware of any such reliable source in geology that contradicts the National Academies' conclusions?Contradicts and in such a big way. Geological and paleclimate data do not provide us with reliable estimations of green-house effect of CO2. The reason is probably that this effect too small in magnitude to be detected among significantly more powerful effects, for example, water vapor dynamics, ocean dynamics, unstablle rates of earth degassing, El-Nino, solar activity changes, orbital fluctuations. So far geolodical and paleoclimate data confirmed the opposite phenomenon, namely, t... Thanks, amgumen. This paper indicates that geologic emissions of CH4 methane, which were not considered in the IPCC-2001 report as a source of atmospheric methane, may account for what appears to be an imbalance in the data on methane sources and sinks in the IPCC-2001 report. It estimates that geologic emissions of methane are 8.5% of the total sources of atmospheric methane, and says geologic sources of methane "cannot be disregarded anymore in the next IPCC assessment reports." This is just an example how much thoroughly IPCC operates with scientific data from adjacent areas of knowledge and how many uncertainties there are in earth sciences to attribute temperature rise (not proven yet that it is global) entirely to human CO2. As for geological sources of CH4, this amount in the article is obsolete already. The scales of CH4 emission from rift and even from platform zones remain underestimated. They are going to rise from year to year. Recent openings of CH4 fluxes change our stand on earth degassing dramatically. If you give me your e-mail I'll sent you other papers. OK, you can take it from here The first study appears to complement the data in the IPCC report regarding natural sources of a portion of the greenhouse gases, and I don't see it as a contradiction of the claim that a reduction in combustion of fossil fuels can reduce the probability of an abrupt climate change. I'll read your second report. the probability of an abrupt climate changeBuches, please don't use this ambiguos terminology - abrupt climate change or give a definition of it. If you are in consensus with paleclimate knowledge you should understand that it is impossible to define what normal and what anbnormal stage is. In the light of previuos catastrophical changes of climate, chance is that a catastrophy will occur again without any human help. Current rise of 0.5-0.6 degrees C per century seems to be a background stage, and no ground for alarmism. If we take into consideration the scientific fact that our planet resided mostly in ice conditions for last 500,000 years, we should be afraid of cooling an... anI apologize for using terms of art that may be unfamiliar to those who haven't read the relevant science. From an earlier clip of mine. Some threshold, a new state at a rate determined by the climate system itselfRead it you wote. Did you find the set of text more audible than abrupt change? Could you please specify in degrees, cm of water sea or other units. Something abrupt happened with such kind of peer-reviewed literature amgumen, your english is terrible, but I think you said that you don't understand the definition I copied above. I would recommend a lesson on basic grammar, and then you can read all about it. National Academy of Sciences: Abrupt Climate Change Chapter 1: Introduction to Abrupt Changes in the Earth's Climate I am really sorry for my English. I just study the new area of knowledge and make a lot of grammar mistakes. My English study enrichs my perception of the world significantly. If you prefer communicate with me in Russian, let me know. Your perception of earth processes is as much as my English. This link added nothing to what I know about paleoclimate. But at last I got from you what I wanted: Changes of up to 16°C and a factor of 2 in precipitation have occurred in some places in periods as short as decades to yearsCould you please confirm that these are thresholds for climate to be abrupt? Is my English clear? Also, it would be interesting to read after Our ability to understand the potential for future abrupt changes in climate is limited by our... OK, I got the whole piece of the narration: Our ability to understand the potential for future abrupt changes in climate is limited by our lack of understanding of the processes that control them. For example, mechanisms proposed to explain abrupt climate shifts do not fully describe the patterns of variability seen in either the paleoclimate or the historical records.As far as we can see, Bushes, your attempt to explain what the abrupt climate change has been vain. The peer-reviewed paper turned out to be useful to define the term. So, what stuff is the consensus based on? Well that was entertaining. Buches, relax. You are clearly out of your league. |
